In other words, their first kiss onscreen, if it's after a separation, really would be like a "first kiss after getting back together", etc. etc.
y'all know what? i don't think they will give us a kiss in some random circumstances. i mean, it won't come out of nothing like VB or IWWU. i think we can expect an emotional episode, where the kiss will be a direct result of the crime-plot or at least stronly connected to the events, and thus, truly excused. considering the number of anti-GSR people, which make about a, what, 15% of an audience (where 50% is pro, and 35% don't care), they still need to be cautious and CANNOT make it a "by the way" scene. also, it's one of the rare times, when the anti-GSR people work for our favor. if this will be a result of emotions, we may see a very intense scene. i mean, if they are doing it, they should do it all the way. i'm not talking about a classical hollywood make out, but about the intensity, the emotions and the circumstances surrounding our Geeks at that time.
so, this all means that the most probable moment that i know of is Grissom leaving or coming back. another thing is, that we assume a goodbye/welcoming scene will be shown because it automatically fits to the scheme of an emotional circumstance, and thus, would excuse a kiss. i agree, but i have a feeling that it would be too obvious. i would be a bit dissapointed if TPTB decided on this easy way to show it. besides, the second we'd see the airport/or their apartament we would know that in the next two minutes they will kiss. i always thought that it would be more of a surprise factor. i still have hope, that it will be shown in a different way.
but if it happens to be a goodbye/hello kiss i'm not gonna complain either.
I'd like to be like you, spoiler-free but I... just... can't!
yeah, i know. everyone would like to be like me cuz i'm so awesome and unique.
lol
ETA:
He slowly backs her further into the wall, a la "Invisible Evidence", and they finish their conversation with whispered "I missed you"s while staring into each other's eyes. Then he slowly leans down, and they share a very soft, slow kiss. Part lips a second - then kiss again. And again. Cue passion, hunger, hottness, etc. And the camera fades to black, 'cause you know it's gettin' all X-rated up in there against the wall any second now....
MissDee, you're genius. just omg. if this was made this way i wouldn't care about circumstances anymore. i'd just have a heart attack and die. period.
